gone for good is extinction
Earlier you said there were 11 letters in "footprints in rocks." If there are 10 = impression/impressions (11)

The footprints in rocks that are left by prehistoric animals are called "ichnofossils". "Ichno" refers to traces or tracks left behind by organisms. These traces can include footprints, burrows, or other impressions.
Regarding the second part of your question, if something is "gone for good," it implies that it is extinct or no longer present. In the context of studying fossils, the term that begins with "e" and has 10 letters could be "extinct". Extinct species are those that no longer exist on Earth.
So, the terms you are referring to are "ichnofossils" for footprints in rocks and "extinct" for species that are gone for good.
